During a special segment of the episode, Heechul who is known to be a huge Sechskies fan battled against the group of guessing the correct Sechskies song. Heechul impressed everyone in the studio as well as the viewers this day with an amazing human-jukebox ability and eventually beating Sechskies in the game. Comedian Lee Soo Geun said, "This game is amazing in itself. How is Heechul playing a game with Sechskies where they guess which Sechskies song it is?"�

After wrapping up the game, Heechul joined the group in covering their old track, "Reckless Love" as if he has always been part of the group.�
